Rat Kiley

"Among the men in the Alpha Company… multiplying by maybe." (Sweetheart of the Song Tra Bong)
Rat is all about hyperbole. Lying, for him, isn't about lying. He's not being malicious, or trying to trick you. He's just improving the truth. He's trying to help you feel exactly what he felt. O'Brien does the same thing throughout the book, although O'Brien is less about hyperbole and more about changing the ways things happened, for better or worse.
